2. DESCRIPTION
Differential consists of 2 main parts:
Final gear: consists of the drive pinion and ring gear, to increase its moment and change the direction of lap 90o Differential gear: consists of a pinion gear side, to distinguish the function cycles between the left and right wheel

3. final gear consists of 2 types:
Ring gear
1. HYPOIDE BEVEL GEAR
Offset
Used at the rear wheel drive vehicle, where the drive pinion is connected with the offset diameter ring gear. benefits, the sound more smooth
Drive pinion
Drive pinion
2. HELICAL GEAR
Used in front wheel drive vehicle. Advantages, noise and vibration is smaller and moment can be moved with the smooth
Ring gear

5. BASIC PRINCIPLES DIFFERENTIAL GEAR
When the vehicle turn, the wheel distance in (A) less than the distance of the outer wheel (B). Thus, the outside wheels must rotate faster than the wheel rotates with the wheel dalam.bila round of the same, then one of the wheels will slip and will cause the worn-out tires faster. It is necessary for differential

6. BASIC PRINCIPLES OF WORKING DIFFERENTIAL
WHEN GO RIGHT
When the second rack are given the same load, when the shackle will be drawn up to the second rack up at the same distance, because the prisoners rack left and right together. So that the pinion does not rotate

7. WHEN ROAD Turn
But when a larger burden placed on the rack to the left shackle and drawn up, the pinion gear rotates along the serration akan rack that get heavier burden because of differences in prisoners. Genesis is the rack that get smaller the burden will be picked up

8. CONSTRUCTION DIFFERENTIAL

9. HOW IT WORKS DIFFERENTIAL
At the time the road is straight
Drive torque ring pinion gear, ring gear torque differential case, differential case through the pinion gear pinion shaft and pinion gear rotate side gear left and right with the same rpm (due to arrest the wheels left and right together), so that the lap wheel left and right same .

10. At the road turn
Drive torque ring pinion gear, ring gear torque differential case, differential case through the pinion gear pinion shaft and pinion gear side gear around the load causing heavy lap wheel left and right not to be the same.

11. CALCULATION OF GEAR RATIO
GEAR RATIO( GR )
Number of ring gear gear GR =
Number of teeth pinion drive
Ring round the number of gear (rpm) the number of teeth pinion drive
Rpm ring gear
rpm side gear right + rpm side gear left = 2

12. AXLE SHAFT Axle shaft classified into 2 Axle shaft rigid
Function: As shoulder wheel load or wheel holder and successor machine to lap the wheels.
Axle shaft classified into 2
Axle shaft rigid
Axle shaft independent

13. AXLE SHAFT MODEL RIGID
Function: Successor to the lap wheel Wheels supporting the l
Axle shaft type often used on rigid vehicles up to medium scale with a large load, also in the vehicle that is designed to field - field is able to withstand the weight of a heavy burden

14. Kind of place :
Front axle
Rear axle
FRONT AXLE
s the wheels of cycles, as well as the knuckle so that the wheel can turn directions

15. AXLE SHAFT
As a successor of the round side to the gear wheels

16. REAR AXLE
Based on the axle shaft penopangan system is classified into 3, namely:   * Half Floating type (half-free shoulder)   * ¾ floating type (3 / 4 shoulder-free)   * Full floating type (free bear) As a successor of the round side to the gear wheels

17. HALF FLOATING TYPE (Half-free shoulder)
On this type of wheel bearing is installed between the axle and axle shaft houshing Paired wheels directly on the tip of the axis
Advantages:    Simple construction    Cheaper production costs Disadvantages : Axle shaft to be bent due to heavy vehicle dipikul by direct-axis If you have broken a wheel does not hold

18. THREE QUARTER FLOATING ( 3/4 load)
Ball is placed between the axle houshing wheel hub and axle shaft, the axle shaft does not directly bear the burden of the vehicle involved
Advantages: Heavy vehicles is not forwarded to all axle shaft so the axle shaft is not bent. When the going axle shaft fracture is still on hold by roller
Disadvantages Due to the style of the style still cause side crookedness

19. FULL FLOATING
Type in the wheel hub is firmly attached to the axle shaft through two roller and axle shaft only serves to drive the wheels.
Advantages: Weight by all vehicles by axle houshing, so that does not happen bent axle Style to the side was not forwarded to the axle shaft Safety factors and better able to bear heavy burdens.
Disadvantages
Expensive production costs

20. HOW WORKING MODEL AXLE SHAFT RIGID
Because of the rigid so that when the vehicle is running as if the position of the vehicle body - it follows the movement of rigid axle position
Advantages: Construction stronger. Suitable for vehicles up to medium scale Able to withstand heavy loads Moment produced large
Disadvantages Hard Suspensi At the time the vehicle is running on a bumpy road vehicle is not stable Turn a small corner of the

21. AXLE SHAFT MODEL INDEPENDENT
This type often used on small vehicles Because in addition to lightweight construction, is also able to turn a big corner.

22. HOW WORKING MODEL INDEPENDENT AXLE SHAFT
Equipped with a CV joint at the time the vehicles go in road the wave, the position of the vehicle body as it were - will not be affected by the road CV joint can be moved next to the play can also sweep, and make a short corner

23. CONSTANT VELOCITY JOINT
Function:
Create a stable position as the vehicle especially on the road - the road is bumpy

24. CONSTANT VELOCITY JOINT
Compoents CV Joint
Outer race
Ball cage
Inner race
Steel ball

25. CONSTANT VELOCITY JOINT
HOW TO WORK WHEN CV JOINT GO RIGHT
At the time the road is straight and flat power play from the forward by differential axle shaft through the inner race houshing - steel ball - intermadiate axle shaft - steel ball - houshing outer race - wheels. At that time, so stell ball still does not form a CV joint angle

26. HOW TO WORK WHEN CV JOINT ROAD TURN
At the road turn or not turn the power of the average differential forwarded by; Inner race houshing - steel ball - intermadiate axle shaft - steel ball-outer race houshing m - wheels. Where at the time as the addition of lap steel shaft from intermadiate ball is also moving on the inner race, so that the CV joint is able to create a corner that allows the vehicle to be stable
